Cornago's activity is attested during the middle decades of the 15th
century, and the Mass is a unique example of the period. It is
contemporaneous with Dufay's cantus firmus settings, and shares the
distinction with the Missa Se la face ay pale
of being the earliest known mass based on a secular tune (track #1).
In general design, it is very similar to Franco-Flemish polyphony of
the period and indeed it has been suggested that Cornago came from
Belgium.

The songs include both lighter and more serious pieces, as well as
several distinct settings of the famous bass-theme, La Spagna. Item #12
is a song by Cornago for which Ockeghem
composed a fourth voice, apparently during his trip to Spain. Indeed,
the Mass has some stylistic similarity to Ockeghem's output as well,
though the tunes are certainly unique. The songs recorded here present
some of the variety of Spain in this period.
